A Santa Rosa man was arrested early Christmas morning after police found him sleeping in a vehicle with a loaded handgun easily within reach, officials said.

At 4:46 a.m., a police offer driving on the 2100 block of West Steele Lane was flagged down by a passerby who told the officer he had seen a man in a vehicle and thought he might be drunk. The officer located Carlos Casillas, 24, sleeping in the vehicle and noticed the gun next to him in the passenger area.
